Answer:
b. passive solar heating
Explanation:
Passive solar heating is a system designed to use solar energy (energy from the sun) for the purpose of providing electricity or heat. This system is used in households and offices to absorb, retain and supply heat to the desired location.
This system is termed "passive" because it does not require any external device for conversion of solar energy rather it exploits sun's energy directly. Hence, according to this question, PASSIVE SOLAR HEATING is the form of renewable energy that uses the sun's energy most directly.
The plane that divides the body into left and right portions
is known as the sagittal plane also known as the median plane. Sagittal plane
bisects the body into two halves and the plane motion occurs around a coronal
axis. Movements in the sagittal plane are the flexion and the extension. The Flexion
movement involves the bending movement in which the relative angle between two
adjacent segments decreases. The Extension movement involves a straightening
movement in which the relative angle between the two adjacent segments
increases. In general, both flexion and extension movement occur in many joints
in the body, which include shoulder, wrist, vertebral, elbow, knee, foot, hand
and hip.
The sagittal plane has two subsections; they are the
Midsagittal and the Parasagittal. The midsagittal runs through the median plane
and divides along the line of symmetry while the parasagittal plane is parallel
to the mid-line and divides the body into two unequal halves.
Not sure but i think cohesion forces
